Have a 2 GHz Intel Core Duo Mac OS X Ver. 10.6.8 - Having AppleMail problems: very very very slow opening any new incoming mail, can't delete, can't assign to Spam, and can't move to any folder for storing, and can't empty trash.  Seems to be corrupted and might need to reload the Mail Program (Version 4.6) and need to know if I can reload the mail program  and if I did would I lose all the data stored in folders?  I don't know how to reload the Mail program.  Also the entire computer seems to be slow to react as well but mail is worse.  I've checked and emptied caches for the browsers I use.  Connecting to Internet all right but as I said, slow to react.  I would appreciate any advice. Thank you.

iMac, Mac OS X (10.6.8)

    How full is your Mail app?

    How full is your iMac's internal hard drive?

    How much RAM installed in your iMac?

    How many other applications do you run in the background while accessing the Mail app?

    Do you run any antivirus software on your Mac? Antivirus software can slow down the normal operation of OS X.

    Do you run any "crapware" like Mackeeper or any other type of "crapware" like so called hard drive "cleaning" apps?

    Your hard drive could be failing.

    With hard drives, it is not a question of IF the drive will fail, but When will it fail.

    If you have your original Snow Leopard disc, I would start up from this disc, when the installer starts, you can go up to the main menu bar and quit the installer.

    From the menu bar, look for the Disk Utility app and run this from the disc. Run the repair disc option on your iMac's internal hard drive.

    While the drive is still still working, I would suggest that you backup any important data ASAP to either optical discs, flash drives or external hard drive that you may need to purchase.

    Should always have a secondary data backup for any important data that resides on the computer itself.

    We need to determine a little more info about your iMac.

    When you click About this Mac in the upper left main menu bar, a popup window appears.

    In this window is a More Info button. Click this button.

    Look for the Mac model number indentifier (my model ID for my iMac is 10,1)

    I believe that your iMac maybe starved for RAM.

    1 GB of RAM is a very bare minimum for running any version of Mac OS X.

    Esspecially low RAM for Intel versions of OS X.

    We need to determine what year and model iMac you have so we can recommend increasing the RAM amount to amount your model iMac can take.


    If you have a lot of documents and folders on your desktop, you will need to take the time to organize these an minimize the amount of items on the desktop. If you have actual folders and documents sitting on the desktop, these could be causing slowdowns on the desktop because your iMac has to process all of these all the time because they are always present on the desktop.


    When you first open mail, the amount of messages are located at the top of the window.

    If you want to know the data size amount, in the left hand panel, you click once on the any of folders and use the key combination Command-I.

    Apple Mail allots 15 GBs total to the Mail application for saving mail.

    You may need to go through all of your mail and start thinning out deleting no longer needed emails. Go through your Inoboxes, sent mail and Junk Mail to delete unwanted emails.

    Also, make sure you empty the trash in the Mail app, too!


    Another thing, make sure you have actually  emptied the OS X Trash icon in the OS X dock and just not put things in the Trash icon. If there is a paper full look to the OS X Trash icon, then you need to actually empty the OS X Trash.

    Your iMac model year is a 2006 model.

    Unfortunately, that year model can only take a maximum RAM amount of 2 GBs of RAM.

    2 GBs of RAM is better the 1 GB.

    Purchase another 1 GB RAM module to max out your iMac's RAM.

    It may help with some of your iMac's performance issues.

    Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (
